Figure i of the, accompanying drawings is @longitudinal sectional View through a truckaxle construction lembodying the principles of my invention. Fig. 2 is a broken detail view in section, showing a slightly-inodiiied construction embodying my invention.

Referring to the accompanying drawings, reference-sign A desi l etes the Iaxle, which is in the forni of e soli har and of any desired size or shape in transverse section, a eylindrical ber being shown es an exeinpliiiceticn. Loosely mounted u onthe axle proper is a sleeve B, shorter in ength than the axle, the axle merely passing' loosely through such sleeve, the ends of the axle rejecting beyond the ends of the sleeve. pon the pro- )footing ends of the axle are .mounted the Wheels@ These may be oi any suitble or desired type of wheel construction, and While herve shown Wheels ofthe spokepet- Atern l do not desire to be limitedor restricted thereto. Esch Wheel is provided with e hub portion D to receive the projecting end of the exile and with a cap E, which is cored out, es

indieted"et F, to form en oil-chamber, the cap ittingover the end o1c the axle, and through this cap may be provided an oil-passage for the introduction of oil to the oilehember. Thispassage may' be normally closed in any convenient manner-as, for in-- stance, by means ofcJ washer G, held in plug H and yieldingly pressed, by Ineens of e s ring. J, into closing relation with respect to t e oil-passage. A solid portion K of the hub D projects or extends into'the chamber F, and through this solid ortion of the hub l form ducts or assages extendin from the oil-chamber to the bearing-s ace `of Specification of Lettere Petent.

the axle. .The Wheels maybe held upon the axle erids in any suitable or convenient Inanner., I have shown a simple arrangement wherein en inner lange'M of the Wheel-hub extends over or surrounds the end of the sleeve B,and in the contacting interior surfoce of the lange extension M of each Wheel end the exterior peripheral surface of the adjecent end of the sleeve yB, I provide cooper atingand corresponding circular grooves N which when brought into registering rele tion form a ifaceway to receive steel balls P,

which when inserted in. the recewoy through e passage or opening l, whichv vcommunicates therewith, are partially' seeted in 'the groove N, formed in the inner surface of the ilenge M, and also in groove 0, i'orrn'ed'in the i peripheral surface lof the adjacent' end of sleeve B, thereby forming e inost simple, in-

expensive, and eiicient retaining device for.

retaining the wheels upon the projecting exle ends and in which seid fastening device is entirely housed and protected. The sleeve B may be provided with vs'uiteble projecting lugs S, forming ineens 'for support ior'the truck" or cer-body T, or the cenhody or truck-frame may be supported in any other suitable, sim le, or convenient manner.

In' F i 2 I leve shown e. rnod'rned arrange-A ment w erein instead of employing a cylindrical axle end an inclosing sleeve therefor l. provide an axle A?, which may be square or other she e in'cross-section, but provided with a. ey indrical end portion B2, on which the Wheel C is `ournaled, the cap portion E of the hub of t e wheel inclosin the end of the journal B2 oli-the axle, the hu portion E being.,r provided with the cored-out chamber F2 andthe oil-passages L2 and the construction of lug H2, Washer G2, and spring J 2 simi- 7lar in a l res ects to the construction above described. owever, instead of the Wheel being retained by the bell construction by meansof a recevvay formed partially in the flange D of the wheellhub andthe exterior surface' of the sleeve B, and in which race Way theballs P are inserted, as in the .con-v struction above described and as shown in Fi l, 4I provide the axle A? With e. coller or .en ar ement K2, which/is surrounded or nclose by a ilange D2 ofthe Wheel, the race- Way' being formed partially in the exterior the interior sur-4 balls AB2 being inserted iufsuchreceivey, es will he plain end epperen't. in this construction of course there is no axial rotation of the axle, the Wheel revolving upon the journal end of the axle being retained by reason of the balls P2 being partially seated in the groove O2, formed in the exterior surface of the collar K2,`and coperating groove N2, formed-in the interior surface of the flange of the Wheel-hub.

From the foregoing description it will be seen that Iiprovide an exceedingly simple economical construction with few parts and Which does not require the nicety of'machinefinish of the various parts. Efficient provision is made for lubricating the bearings of the Wheels upon the axle. The structure is strong andidurable, the axle proper being preferably a solid steel bar, and the sleeve B eing of iron the wear is reduced to a minimum. i l It is obvious that the design of the various parts may be altered or varied to suit any requirement and that variations and changes in the details of construction might readil occur topersons skilled in the art and stil fall Within the spirit and scope of my invention.

What I claim as new and useful and of my oWn invention, and desire to secure by Let-v chambered inclosing cap for the ends of the -a-xle and Witha flange to receive the adjacent ends of the sleeve., and a raceway formed partially on the inner surface of said flange and the outer surface of said sleeve, a passage through the hub and communicating vvith the raceway, and retaining-balls received Within said raceway through the passage an being entirelyhoused therein. l

2. The combination of a sleeve, an axle extending longitudinally through. said sleeve, and having its ends projecting beyond the ends of said sleeve, Wheels mounted upon the projecting ends of said axle, each Wheel having a solid hub portion to form a bearing.' to receive the end of the axle", and' an inclosilng cap to form a chamber, the solid portionl of said hub having ducts or passages leading from said chamber to the bearing to the'axle end, saidhub also having a flange to engage over the end of said sleeve, and means interf posed between' the bearing-surfaces of said flange and sleeve for retaining the Wheel upon the axle.

3. The combination of a sleeve having an exterior circumferential groove at each end thereof,l an axle extending longitudinrlly through said sleeve and wheel mounted upon Ieach end of said axle,

having its ends pro- .jecting beyond the ends of said sleeve, a

each Wheel having a bored hub and provided on one face of such hub with an inclosing cap forming a chamber and on the other face with a fiange, said flange engaging the end of the sleeve and having a corresponding interior circumferential groove formed therein, and means seated in said grooves for, -etain in said Wheel u on the axle end.
